Blue water-gas: Air, water or producer gas produced from clean fuels such as coke, charcoal and anthracite which contain insufficient hydrocarbon impurities for use as illuminating gas. Blue gas burns with a blue flame and does not produce light except when used with a Welsbach gas mantle .
Water gas is a kind of fuel gas, a mixture of carbon monoxide and hydrogen. It is produced by "alternately hot blowing a fuel layer [coke] with air and gasifying it with steam". It is produced by "alternately hot blowing a fuel layer [coke] with air and gasifying it with steam".
As produced, biogas contains water vapor. The fractional volume of water vapor is a function of biogas temperature; correction of measured gas volume for water vapour content and thermal expansion is easily done via simple mathematics [23] which yields the standardized volume of dry biogas.
In the 1850s, processes for making Producer gas and Water gas from coke were developed. Unenriched water gas may be described as Blue water gas (BWG). Mond gas, developed in the 1850s by Ludwig Mond, was producer gas made from coal instead of coke. It contained ammonia and coal tar and was processed to recover these valuable compounds.
It was discovered that adding steam to the input air of a gas producer would increase the calorific value of the fuel gas by enriching it with CO and hydrogen (H 2) produced by water gas reactions. Producer gas has a very low calorific value of 3.7 to 5.6 MJ/m 3 (99 to 150 Btu/cu ft); because the calorific gases CO/H 2 are diluted with much ...
The heat of combustion of "producer gas" – a term used in the United States, meaning wood gas produced for use in a combustion engine – is rather low compared to other fuels. Taylor (1985) [7] reports that producer gas has a lower heat of combustion of 5.7 MJ/kg versus 55.9 MJ/kg for natural gas and 44.1 MJ/kg for gasoline. The heat of ...
Bulk heating, electric generation, and engine-running uses; also for welding purposes, as it possesses a "reducing flame" and a high temperature. N.B. One variant of producer gas was Mond gas, known for both its consistent yield and that ammonia could be obtained as a byproduct. Slight modifications of producer necessary. Water gas
Gas blending is the process of mixing gases for a specific purpose where the composition of the resulting mixture is defined, and therefore, controlled. A wide range of applications include scientific and industrial processes, food production and storage and breathing gases.
